That is one of the worst "puppy cuts' I have seen. That groomer had no idea what they were doing, they shaved her body and left her head untouched, kinda looks like a lion cut. I took trixie in once and they did the opposite, they shaved her muzzle and cut her hair on the head really short and left the body long. So now aI always groom my babies myself, there are just too many bad groomers out there. I would like to say, even though they butchered your baby she is still gorgeous, not even a groomer could take that away from her!!!
She looks kinda scared in the picture, poor girl. Don't worry it will grow back and although it is not your ideal cut that you had in mine, she is still adorable.
